Aliens: Colonial Marines patch fixes a lot of things, even the flamethrower

Clean up on aisle Aliens: Colonial Marines – Sega launched a patch to address a few of the issues in Colonial Marines, including various visual improvements, improved texture resolution, audio fixes, increased enemy and friendly AI responsiveness, modified enemy collision detection and NPC navigation, fixed spawning issues, removal of the ability to walk outside of maps, and many more, listed in full below.

Our favorite from this extensive list has to be, "Addressed an issue where Ripley's Flamethrower (bonus content) would sometimes fire continuously without player input." The update should automatically install on Steam, so unfortunately there's no way to keep that particular glitch (feature?) in your game.
